So, I had one key in the car to run it and get it warm and i locked it with my other key. now the keyless entry won't work -- are they out of synch or WTF??? I tried the synch method in my manual ('99 1.8T A4) and its as clear as mud. Press the button and then lock or unlock the door. I did just that and nothing -- is there more of a trick? Need help ASAP -- it's cold as **** out there! LOL!
